#All saving accounts have different interest rates based on the deposit amount. In one 
#bank for example, if the deposit is 1000 dollars or less, the interest rate is 1% per 
#year, otherwise the interest rate is 2% per year. Write a program that inputs deposit 
#amount. Program calculates and prints the amount of money that will be in your saving 
#account after one year. Apply the interest rate rule which is described above. Bonus: 
#Program checks first, that the input is valid (deposit amount is positive) For 
#invalid input, program prints error message. 

#Input: deposit, float, >=0
#Calculations: if/else to determine interest rate (1 or 2 percent, we 
#will store this value in variable interest), final=deposit*(1+interest/100)
#Output: final, float, >=0

#Input

deposit=float(input("enter initial deposit "))

if(deposit>=0):
	if(deposit>1000):
		interest=2
	else:
		interest=1

	final=deposit*(1+interest/100)
	print("after 1 year you have", format(final,'.2f'))

else:
	print("Invalid input")
